Storage
Materials should normally be stored under cover. Reduced shelf life may occur if packaging is exposed to the elements. Packaging materials may deteriorate, allowing moisture ingress into the cementitious binder. This could lead to premature hardening.
Shelf Life
Roof Bolt Grout products will store for up to 6 months in dry conditions.
Safety
| General | The use of eye protection, gloves and dust masks is recommended. Follow the typical precautions as prescribed for handling Portland cement. |
| Inhalation | Constant exposure over long periods of time to very high concentrations may cause a cough with phlegm. |
| Skin contact | Prolonged exposure could sensitize skin causing mild irritation. In extreme cases, dermatitis could occur. |
| Eyes | Use eye protection. However, if eyes become affected, irrigate eyes with copious amounts of clean water. Seek medical attention. |
| Ingestion | Ingestion of harmful quantities is unlikely to occur. If ingested, drink copious amounts of drinking water and consult a medical practitioner. DO NOT INDUCE VOMITING. |
